Times on Servers/Client PC's

Kerplunk · 12 Oct 2010 at 07:05

Hi guys,

This may be a simple one or maybe you can tell me!

How do I go about changing the Windows time clocks on all the client PC's/Servers?

Is there a place where you have to set the time? DC server? How do they all stay in sync?

At the moment our times on PC/servers are all 5 minutes slow

Many thanks

By default domained computers get their time from the DC. So if you change it in the DC, the clients should follow suit.

Just an FYI sometimes in a virtualised environment the time on the host machine will feed down to the virtual machines but like Sirius said, in a domain environment they will feed off the DC

Ok, thanks - So is it a case of set the desired time and reboot the server and jobs a goodun? Or will all machines/servers need to be rebooted?

IIRC they dont need to be rebooted. The time sync goes at a specified interval which I cant remember.

That is my understanding too.

It might take a few hours for all clients to catch up.

You can try

Code:

w32tm /resync /rediscover /computer:<computer1>,<computer2>,<computer3>

Worth considering configuring the authoritative time server to sync from an NTP server.

I don't know if anyone else does, but I set most servers to use the uk ntp pool.

The two freeware tools here might be of interest.
